ABSTRACT
Optimising travel around a city while reducing CO2 emissions and urban traffic congestion has led to major road tunnels becoming an increasingly in-demand infrastructure in localities with aspirations to “smart cities”. Such infrastructures are very often the star projects of the cities that embark on these projects and expectations for them are increasingly high in terms of performance, sustainability and social and environmental impact. It is also a type of project which has made significant technical advances in the past 10 years in regards to design, construction methods and control systems.
The Legacy Way Project in Brisbane is a good example of this. The tunnel was recently opened to the public, in May 2015.
